Unfallbericht:Approaching Sioux Lookout runway 16 after a flight from Red Lake the Metro collided with a Piper PA-31-350 Navajo Chieftain (C-GYPZ) operated by Air Sandy. The Piper aircraft had just taken off from Sioux Lookout runway 34 and was climbing through 4500 feet on its way to Red Lake when its right wing collided with the Metro's right wing. The accident happened in daylight (13:30 LT) with a visibility >15 miles and a 8000 feet cloud base.

PROBABLE CAUSE: "Neither flight crew saw the other aircraft in time to avoid the collision. Contributing to the occurrence were the inherent limitations of the see-and-avoid concept which preclude the effective separation of aircraft with high closure rates, the fact that neither crew was directly alerted to the presence of the other aircraft by the Flight Service specialist or by onboard electronic equipment, and an apparent lack of pilot understanding of how to optimise avoidance manoeuvring."

The Department of Transport expedite the development and implementation of safe separation procedures for the use of GPS in navigation.

The Department of Transport ensure that aircraft are flown at reduced airspeeds, consistent with safe manoeuvring, in the vicinity of aerodromes where separation relies primarily on the see-and-avoid concept.

The Department of Transport conduct an analysis of the benefits of requiring commercial passenger-carrying aircraft to be equipped with TCAS versus the risks associated with operating aircraft without TCAS.
